Who's running the best cat-back?

Ladies and Gents,
I gotta choose between the GReddy SP exhaust system, and the HKS Drager System for my Primera (SR20). Please share some experience with me.
:help:

I'm using the HKS Super drager & i'm well impressed.
It is a lovely fit, seems to have smoothed out acceleration & its
no louder than stock (just a slightly different note).
I love the 4" slash cut pipe so I'd certainly recommend it.

Im using magnaflo exhaust....2.5 inches catback......feel smooooth...not loud or not too silent.......Im out.

Greedy MX phat sound! I love it! :alien: :bloated: :licker: :smoka: :flash:

ive got the greddy evo cat-back noticed a big difference love the sound, But i wish the tip was just a little smaller
Sleepy

HKS dragger is prolly one of THE sickest exhausts I have ever seen witht he exception of the APEXi Worldsport which I cream my pants over. However since they don't make the APEXi worldsport for your cars, the Dragger is the best.

What kinda price can I get the HKS Drager System for?

Greddy MX cat back is so freakin' good..., I can't even get it. GPP has a backed order and it would take 3-4 weeks to get it!!! Shoot! I need it so bad! I might settle for REMUS muffler. Does any of you guys know how well it is made. How do you compare it with Greddy or HKS. The price is $350.97 not including shipping I believe? And it's only the muffler part, not including the intermmediate pipe.

Goin by GT UK's dyno results i wouldnt bother paying £500 for a hks cat back im running a standard GT primera cat back with a powerflow muflfer (cheap uk custom made one its blowing at the joins from the back box to mid section cheap pish!) but it dont seem to hurt my hp frigures... 162 hp.
